According to the feature of the present invention, disclosed is an infant tricycle having a backrest angle adjustment function. The infant tricycle comprises: a main frame (110) having a front wheel (111) mounted on a front side thereof and a rear wheel (112) mounted on a rear side thereof; a hip support unit (120) arranged in a horizontal direction and mounted on an upper portion of the main frame (110); a backrest unit (130) having a lower part axially coupled to a rear side of the hip support unit (120) to be rotated back and forth and angle-adjusted; and a tilting control unit (140). The tilting control unit (140) comprises: a driving frame (141) having one end axially coupled to the pivot center of the hip support unit (120) and the backrest unit (130), the other end fixed to the backrest unit (130), and a plurality of adjustment holes (142) spaced apart from each other to be laterally opened on a rotation radius spaced apart from the rotation center by a predetermined distance; and an operation frame (145) mounted on the hip support unit (120) at a side of the driving frame (141) so as to be laterally movable, having an insertion protrusion (146) formed in a shape corresponding to each adjustment hole (142) to be laterally protruding from a position at which the rotation radius of each adjustment hole (142) is overlapped with each other, and having an insertion protrusion (146) laterally moved by a user′s manipulation, such that the insertion protrusion (146) is inserted into any one adjustment hole (142) to support an angle-adjusted state of the backrest unit (130).

    본 발명의 특징에 따르면, 전방에는 전륜(111)이 장착되고 후방에는 후륜(112)이 장착되는 메인프레임(110); 수평배치되어 상기 메인프레임(110)의 상부에 장착되는 둔부받이부(120); 상기 둔부받이부(120)의 후방측에 하부가 축결합되어 전후로 회동하며 각도조절되는 등받이부(130); 및 일단은 상기 둔부받이부(120)와 등받이부(130)의 회동중심에 축결합되고 타단은 상기 등받이부(130)에 고정되며 상기 회동중심으로부터 일정거리 이격된 회전반경 상에는 측방으로 개구된 복수의 조절공(142)이 이격배치된 구동프레임(141) 및, 상기 둔부받이부(120) 상에서 상기 구동프레임(141)의 측부 위치에 측방이동 가능하게 장착되고 각 조절공(142)의 회전반경이 중첩되는 위치에는 각 조절공(142)과 대응되는 형상으로 측방 돌출된 삽입돌기(146)가 형성되며 사용자 조작에 따라 측방이동되어 상기 삽입돌기(146)가 어느 하나의 조절공(142)에 삽입되면서 등받이부(130)의 각도조절된 상태를 지지하는 조작프레임(145)을 포함하는 틸팅조절부(140);를 포함하는 등받이 각도조절 기능이 구비된 유아용 세발자전거가 개시된다.
